It sounds like a good approach with all of the caveats you outlined. Here are a few fill ins that may help round out the plan:

-If your balance exceeds contributions, the MBCBP can be rolled into an IRA at 59 1/2.
-A Roth IRA doesn't have the same legal protection as your 401k, but it will match or exceed the protections of the brokerage account it replaces,
-The 401a to Roth IRA can be taken one step further into a Roth SDIRA for an even wider range of investment options.
